PS2581AL2-F3-A

Overview

The PS2581AL2-F3-A is a single-channel transistor output optoisolator manufactured by Renesas Electronics Corporation. It features a 4-SMD (gull-wing) package and provides an isolation voltage of 5000Vrms. The device utilizes an NPN phototransistor output with a maximum collector-emitter voltage of 80V and a collector current of 50mA. Key electrical parameters include a forward voltage of 1.2V, a saturation voltage of 300mV, and rise/fall times of 3µs/5µs. It operates within a temperature range of -55°C to +100°C.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits
• Features fast switching speeds suitable for digital signal transmission
• Offers stable performance across a wide industrial temperature range

Applications

• Industrial automation control systems
• Power supply feedback loops
• Microcontroller interface isolation

Procurement Notes

Verify the specific suffix F3-A confirms the tape-and-reel packaging format required for surface-mount assembly processes. Confirm RoHS compliance status and check for any recent Product Change Notifications regarding lead finish or manufacturing site changes before finalizing procurement orders.

Selection Notes

Select this component when surface-mount technology is required for single-channel isolation. Ensure the 80V collector-emitter voltage rating meets the load requirements. Compare against through-hole variants like the PS2581AL1-A if PCB space constraints differ or if manual assembly is preferred over automated placement.

Part Context

This part belongs to the PS2581 series of single-channel optocouplers from Renesas. It shares functional similarities with other members of the family but differs in package type. The AL2 designation typically indicates the SMD gull-wing configuration, distinguishing it from the DIP versions within the same product line.

Replacement Considerations

PS2561L2-1-F3-A is listed as a parameter-equivalent alternative from the same manufacturer.
